- To all whom it may concern:

all)

lBe it known that 'l, .losnrn H. Tnnrmn. a citizen of the United" States, residing at Philadelphia, in the county" of Philadelphia andState-of Pennsylvania, have invented certain new and usefulllmprovements' in Vacuum Renovating Apparatus, oi which the followingji's aspecification. My invention relates to improvementsin vacuum renovating apparatus inwhich means for producing- .a vacuum -are .emplo'yed. i

in a prior application filed July 23rd, 1909, Serial Number 503,969, i have shown a system of cleaning wherein a vacuum is employed While in this application which is filed as a division and continuationci'said prior application I claim the meansshown therein for creating the vacuum." 1 The object. of my invention is to produce a \acuum pumping mechanism requiringthe least amount of power for drivingsame, also simple and durable in construction'las well as light in. weight consistent with ts capacity, and furthermore to reduce the v1- bration to a minimum. I

To accomplish the above purpose l have arranged and constructed my ap aratusas follows: A main casing supporte on a base has an upper or vacuum chamber rovided with an inlet and a coverysaiol in ct being adapted to receive the well known suction hose end. Said vacuum chamber also contains a suitable dust separating device. in the lower portion of the casing is located the vacuum pumping mechanism, the inlet of said pumping mechanism being connect ed to the vacuum chamber and adapted to exhaust the air therefrom. Means for driving the pumping mechanism are located on a base to which said pumping mechanism and main casing are also secured, the whole thereby forming a compact and truly porta ble machine.

Referring to the drawings in which similar letters of reference indicate like parts, Figure 1 represents a side view of my apparatus partially in section wherein the mechanism is motor-driven, and showing two double acting pumpsw Fig. 2 is a side view of another construction also partially in section wherein one double acting pump is motor-driven Fig. 3 is a side View, partially in section oi my apparatus as con .structed to operated by hand. Fig. 4c is section of a plait shown extended. Fig. 5 is a sect on ot "a plait shown compressed. Fig. ti shows another form of construction wherelna single flexible diaphragm is 'used instead of the plaited form.

1 in the drawings 1 the main casing, Q't'lie vacuum chamber and 3 the cover fo'r same, istl'ife'inlet tosaid chamber adapted torepe 1ve the' uction hose 6 is a. well lmowrl'renovator attached to the opposite end of said hose 5 and through which'the dust-laden air passes into the vacuum chambee; the el tist being deposited into? the separat ng device, the purified air passing through 'the orifice 7 into the inlet 8 of the 'vacuiunprod'ucing means.

9 is the hase'to wliiehthe casing l is se cured. IO is the frame of thepump'ing mechanism which is als'o secured to'base 9.

It and 12 are the inlet and outlet valves, located in' 'their respective chambers in ir'anie'lO.

i3 is the outlet of chamber 14, said outlet being" adapted to receive the end of the well known blowing hose 15.

"16 are collapsible chambers formed in each side of 'frame 10. "These chambers in mypreterabletlesign are formed by 'hel lows shaped plaits 17 secured at their joints by stiffening rings IS-as shown,whereloythe plaits l? retain their form under any conditions of vacuum or pressure to which. same may be subjected. The plaits 17 are adapted to be extended or compressed by means of plates 19 which are connected to each other by yoke 20. By means of crank rod 21 one end'being pivoted to yoke '20 at 22 the other end being operatively con nected to-crank pin 23 reciprocating motion is imparted to yoke 20, as shown in Figs. 1 and Qorby means of link 24- connected to yoke 20 by pin 25 and to hand lever 26 by pin 97, said lever being pivoted to bracket 28 by means of pin 29 Fig. 3.

30 is the motor shaft on which. crank 31.

is secured, said shaft receiving its. rotary auction. from motor 32.

33 is the electric cable attached to the motor and 34 is a plug attached to the free end of the cable and adapted to be attached to the'ordinary electric light socket, where'-- loy connection is made to the source pr power or drivmg electric current.

From the foregoing the operation of the mechanism may be readily understood, current being turned on by the operator at the switch causes rotation of the motor shaft and cranks, thereby imparting reciprocating motion to the yokes which alternately compress and extend theplaits or diaphragms thereby causing alternately inrushes of air 'into the inlet of the pump and through the inlet and outlet valves which operate alternately. The inrushing air into the pump causes an inrush into the renovator, carrying with it any dust to which same may be brought into contact, and depositing same into the separating device, the purified air passing through the pump into the open air or may be utilized for blowing purposes.

' It will now be seen that in my construction I reduce themachine to a compact form and reduce the friction of moving parts-to a minimum as I have no piston rods or glands nor guide blocks and rods and no possibility of leakage from extra joints of stuffing i boxes.

. WhileI have shown my preferable design I do not wish to be limited to the exact details. of same as changes may be made by thoseskilled in the art, which changes may I come within the scope of my invention.

Having thus described my invention, what I claimas new and therefore desire to secure" a y Letters Patent i r 1, .A vacuum pumpincluding in combina I tion, a fixed frame having inlet and outlet 35 ports and valves for closing the same, movable plates, flexible annular 'diaphragms connecting said movableiplates to said fixed frame, said diaphragms being hermetically secured to eachother at their inner edges, stifieni'ng rings secured to said inner joints for clamping the edges of said diaphragms together, and means for reciprocating said "plate, said reciprocating means inclu ing a yoke surrounding the frame and supported by said movable plate. I

3. A vacuum pump including in coml ination a fixed frame having inlet and outlet ports and valves for closing the same, movable plats at each side of the frame, flexible annular diaphragms connecting said movable plates to said fixed frame, said din-- phragms being hermetically secured to each other alternately at their inner and outer edges. respectively, stiffening rings secured to said inner and outerjoints for clamping the edges of said diaphragms together, and

means for reciprocating said plates, said reciprocating means including a yoke surrounding the frame and supported by said movable plates. a

.In' testimony whereof I afiix my signature in presence of two witnesses.
